Description of Related Art

Exposing a cell phone to an outside heat source is the most common cause of overheating. Leaving a phone sitting directly in the sun, inside a hot car or under a lamp that produces heat can cause the phone to feel hot to the touch. Particularly harmful is to expose the battery to heat when it is fully charged, as the battery will be periodically checked and charged back up to 100 percent, applying stress. Depth of discharge also affects battery life, meaning it is best not to let the charge run down to zero percent. Anything over about 30 degrees centigrade will start negatively impacting a lithium-ion battery, and this is a temperature phones typically climb above every time charging occurs.

With temperatures consistently reaching the high nineties or more, leaving a phone in a vehicle can quickly lead to overheating. If a phone needs to be left in a vehicle, it should be tucked away in a shady spot. This protective action may not completely stop the phone from reaching high temperatures, but it will be much safer than leaving it in direct sunlight.

It is known that smart phones are sensitive to environmental conditions. By way of example, temperatures in excess of 95° Fahrenheit, as well as temperatures less than 32° Fahrenheit, can negatively affect the performance of a cell phone. Some smartphones list the optimum range of temperatures in their technical specification. For example, when the phone is turned off, an iPhone can withstand temperatures between −4° and 113° Fahrenheit. When the phone is turned on, the range is much narrower. Apple suggests 32° Fahrenheit as the lowest operating ambient temperature. Other phones are rated for much lower temperatures, and some can go as low as −4° Fahrenheit while in operation.

When lithium-ion batteries are exposed to cold temperatures, their performance suffers. When cold, a phone battery can drain faster than normal, or it might indicate it has ample power remaining and then suddenly go dead. The problems are only temporary, and the battery should behave normally when the device is brought back up to warmer temperatures. Heat affects mobile phones, mobile laptops and mobile tablets that are exposed to the sun or heat when, for example, they are exposed to direct sun when located on a boat or left in a car during the summertime. Cold affects mobile phones, mobile laptops and mobile tablets that are exposed to cold ambient temperatures when, for example, being utilized on a ski slope.

Dropping a cell phone can cause damage to multiple portions of a cell phone. Cracked glass is one of the most common forms of damage to broken cell phones. The glass can crack when a phone is dropped or accidentally stepped on or crushed while leaning against an object. Manufacturers are trying to make cell phones sturdier as the devices become more advanced, but smartphone screens are still made of breakable glass.

Dropping of a cell phone can affect the cell phone buttons. Buttons that do not work or stick are functionally problematic. Nonfunctioning buttons affect the ability to text, search the Internet, and dial the phone. Buttons may stop working because of a cell phone's circuits being exposed to moisture or heat or become broken as a result of a drop.

Cell phone speakers can stop working due to loose or corroded internal parts, or damaged hardware from dropping the phone. There is a need for an environmentally protective sleeve for a cell phone, smart phone, laptop, or tablet that protects these mobile electronic devices from overheating, extreme cold, damage from being dropped, and damage from water.

It is known that one's cell phone is a carrier of microbes, including bacteria and viruses. Studies have found pathogens on cell phones, including Streptococcus, MRSA, and even E. coli. Viruses can also be spread by contact with cell phones if one person is sick with strep throat or influenza and coughs on their cell phone before handing it off to a friend, by way of example. A 2004 study by the University of Arizona found the typical worker's desk, which tends to be where one places a smartphone for about 40 hours a week, has hundreds of times more bacteria per square inch than an office toilet seat. Separately, according to a 2011 study done by researchers at the London School of Hygiene & Tropical Medicine, found fecal matter on 1 out of every 6 cell phones tested. And, “Mobile phones have become veritable reservoirs of pathogens as they touch faces, ears, lips and hands of different users of different health conditions,” researchers observed in a 2009 study of bacteria removed from personal calling devices.

Thermal signatures (such as an IR signature) are known, as are ways to mask the thermal signature with a reflective material like that of metalized Mylar. Such masking has been utilized for security, military and law enforcement. However, while masking the thermal signature of the individual or a piece of equipment such as a military tank, the reflective material draws attention to an adverse distant observer by way of its reflection of light. There is a need for a material that will mask a thermal signature while minimizing reflective light. Such material, as taught herein, may also be used to protect an electronic device from damage.

SUMMARY OF THE INVENTION

According to embodiments, the present invention provides a protective sleeve for an electronic device, such as, by way of example only, that of a cell phone, mobile phone, pager, laptop computer, tablet computer, or camera. In other embodiments the protective sleeve is utilized for maintaining a certain safety range of temperature for thermally sensitive medications such as, by way of example only, epinephrine or insulin, that a person may carry with them. In aspects, the thermally sensitive medications for insulating and/or protecting may be contained in, by way of example only, a bottle, a syringe, a vial, a cylinder, a bladder, a vesicle, a packet, a box, foil, plastic, or combinations thereof, and the sleeve or capsule described herein not only protects the medication but also is capable of protecting the medication's container. In aspects, the medication may be stored in an EpiPen®, alternative to EpiPen®, or epinephrine injector or auto-injector, which is stored or held in the protective sleeve or capsule. The protective sleeve also provides impact protection should the case be dropped with an electronic device inside and provides the ability to float with an electronic device housed therein should the protective case be accidently dropped into body of water. The protective sleeve may have multiple layers, including a reflective layer, one or more insulating or durability layers, which may include a buoyant layer, and a protective layer. In embodiments, the layers may also be referred to as surfaces. In embodiments, the reflective layer is the outermost layer. The reflective layer can be made of metalized Mylar® or a material with similar reflectivity and can have an emissivity within a range of about 0.05 to 0.40. In embodiments, the protective sleeve includes a buoyant layer disposed between the outermost layer and an innermost layer, which can be made of foam or other buoyant material with a thickness in the range of about 0.12 inches to 1 inch. The foam layer can be made of a closed cell foam material. In aspects, closed cell foam provides better water resistance and a higher level of buoyancy than open cell foam, thus providing a better level of buoyancy protection for the stored electronic device. However, in certain other embodiments, the foam layer is made of an open cell foam material. In embodiments, the protective layer is the innermost layer (i.e. closest to the electronic device) and is made of fleece, microfleece, or similar material. In embodiments, the innermost layer containing fleece or microfleece can serve as an insulating layer or as both an insulating layer and a protective layer. In certain embodiments the innermost layer closest to that of the electronic device can be that of an antimicrobial layer. In certain embodiments the innermost layer can be both that of an insulating layer and an antimicrobial layer. In certain embodiments the innermost layer can be that of a protective layer and an antimicrobial layer, such as, by way of example only, that of an Agion antimicrobial treated fabric, Agion treated polyester, and/or Agion treated textiles. In certain embodiments the innermost layer can be that of an insulating layer, protective layer, and an antimicrobial layer. In certain embodiments the antimicrobial agent is present on the side of the innermost layer facing the electronic device. In certain embodiments the antimicrobial agent is present throughout the innermost layer facing the electronic device. In embodiments, the protective sleeve can include only 2 layers of those described above or can include 3 or even 4 or more layers. According to embodiments, the electronic device or thermally sensitive medication that can be housed by the thermal protective sleeve can be by way of example only, that of a smart phone, cell phone, mobile phone, laptop, tablet, camera, epinephrine, or insulin.

The antimicrobial agent can be limited to the side of the innermost layer of the protective sleeve closest to the electronic device or thermally sensitive medication. The antimicrobial agent can be found within the innermost layer of the protective sleeve. The antimicrobial agent can be contained within both sides of the innermost layer adjacent to the electronic device or thermally sensitive medication. The antimicrobial agent can be found throughout the protective sleeve. The antimicrobial agent can be found within 2 or more of the layers of the protective sleeve. The antimicrobial agent can be found within the innermost layer, the outermost layer, or both. Thus, the innermost layer may comprise an antimicrobial agent, the outermost layer may comprise an antimicrobial agent, or both the innermost layer and the outermost layer may comprise an antimicrobial agent. In aspects, the antimicrobial agent is located adjacent to the temperature sensitive pharmaceutical or electronic device.

The antimicrobial agent used can be one or more biocides acting in different ways according to their chemical and structural nature and affinity level to certain target sites within microbial cells. Those different modes of action may be:

-   -   a. Damage or inhibition of cell wall synthesis, which is         critical for the life and survival of bacterial species;     -   b. Inhibition of cell membrane function, which is an important         barrier that regulates the intra- and extra-cellular flow of         substances, and could result in the leakage of vital solutes for         the cells' survival;     -   c. Inhibition of protein synthesis, which is the basis of cell         enzymes and structures, consequently leading to the death of the         organism or the inhibition of its growth and multiplication;     -   d. Inhibition of nucleic acid synthesis (DNA and/or RNA) due to         the binding of some antimicrobial agents to components involved         in the process of DNA and/or RNA synthesis. This inhibition         interferes with normal cellular processes, compromising         microbes' multiplication and survival; and/or     -   e. Inhibition of other metabolic processes, for instance the         disruption of the folic acid pathway, which is essential for         bacteria to produce precursors important for DNA synthesis.

The following table includes examples only of antimicrobial products or microbicidal materials; including a listing of their major antimicrobial mechanism of action.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS OF THE INVENTION

Reference will now be made in detail to various exemplary embodiments of the invention. It is to be understood that the following discussion of exemplary embodiments is not intended as a limitation on the invention. Rather, the following discussion is provided to give the reader a more detailed understanding of certain aspects and features of the invention.

As used herein, the term “about” is understood as within a range of normal tolerance in the art, for example within 2 standard deviations of the mean. The term “about” can be understood as within 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, 0.5%, 0.1%, 0.05%, or 0.01% of the stated value. Unless otherwise clear from the context, all numerical values provided herein are modified by the term “about.”

As used herein, the term “metallized” (as in “metallized” Mylar®) refers to a material such as a polymer film which has been coated with a thin layer of metal, such as aluminum, chromium, or nickel, typically through a physical vapor deposition (PVD) process. The thin layer of metal can be coated on one surface of the material or both surfaces.

As used herein, the term “laminated” (or variations including “laminate”, “lamination”, and the like) refers to the process or result of creating a composite material by joining two layers together, typically under heat and pressure and/or through use of an adhesive.

As used herein, “Mylar®” may be used interchangeably with “biaxially-oriented polyethylene terephthalate (PET) film”, “polyethylene terephthalate (PET) film”, “polyester film”, and similar terminology.

According to embodiments, the protective sleeve may include two layers (outer, inner), three layers (outer, middle and inner), or four layers (outer, first middle layer, second middle layer, inner layer). In embodiments, the protective sleeve may include one or more layer of material in any number of layers. One or more of the layers of the protective sleeve may be bonded together or may not be bonded together. In embodiments, some, all or none of the layers of material of the protective sleeve may be bonded to another layer in the protective sleeve. In embodiments, some, all or none of the layers of material of the protective sleeve may be bonded to another layer in the protective sleeve. In embodiments, some, all or none of the layers of material of the protective sleeve may be joined together.

Various embodiments described below include a reflective layer such as a metallized Mylar® polyester film laminated to another material such as a Rip Stop Nylon to create a composite material. According to embodiments, the reflective layer may have a reflective surface (e.g. a surface which includes a thin metallic film which is deposited through metallization) and a non-reflective surface, or two reflective surfaces. In some embodiments where the reflective layer has one reflective surface, the composite may be manufactured such that the non-reflective surface is bound directly to the Rip Stop Nylon, such that the reflective surface remains exposed. In other embodiments where the reflective layer has one reflective surface, the composite may be manufactured such that that the reflective surface is bound directly to the Rip Stop Nylon such that the reflective surface is hidden. In embodiments where the reflective layer has two reflective surfaces, one reflective surface will be bound directly to the Rip Stop Nylon and hidden, and one will remain exposed. Thus, in embodiments of the protective sleeve which follow, a reflective surface may face outward (away from the electronic device), inward (toward the electronic device), or both inward and outward. The orientation of the reflective surfaces will depend on the particular application of the protective sleeve (e.g. whether it is intended to protect the device from heat, cold, or both). Further, the reflective surface(s) may be hidden (e.g. covered by another layer) or exposed. Not wishing to be bound by theory, it is the reflective surface(s) of the reflective layer which are believed to primarily trap/reflect infrared energy within or keep infrared energy out of the protective sleeve.

A two-layer embodiment of the invention provides an outer reflective layer and inner protective layer. The outer reflective layer may include Mylar® polyester film, such as a highly-reflective “continuous” metalized Mylar® polyester film, or aluminized polyester film laminated to a Rip Stop Nylon or similar material, and the emissivity of the outer layer may be in the range of about 0.05 to 0.40, such as less than 0.40, less than 0.30, less than 0.20, or less than 0.10. For example, the emissivity can be 0.1 to 0.2, or 0.02 to 0.35, or 0.01 to 0.25, or 0.04 to 0.15, and so on. Further, in embodiments, the outer metalized surface of the outer reflective layer has a reflectivity in the range of between 80% and 100%, with a preferred range between 90% and 100%. The inner protective layer may include a micro-fleece type material (lining) which is capable of protecting the touch screen on the device and preventing scratches.

A three-layer embodiment provides an outer reflective layer, a middle insulation/air space layer, and an inner protective layer. The outer reflective layer may include Mylar® polyester film such as a highly-reflective “continuous” metalized Mylar® polyester film, or aluminized polyester film laminated to a Rip Stop Nylon or similar material, and the emissivity of the outer layer may be less than 0.40 (0.05-0.40 is a preferred range), or in any range provided herein. Further, in embodiments, the outer metalized surface of the outer reflective layer has a reflectivity in the range of between 80% and 100%, with a preferred range between 90% and 100%. The middle insulation layer may include ⅛-⅜″ thick insulation foam (which can be either open cell or closed cell) which provides buoyancy and additional drop/shock protection for the device. The inside protective layer may include a micro-fleece type material (lining) which protects the touch screen on the device and prevents scratches.

A first four-layer embodiment provides an outer reflective layer, a first middle insulation layer, a second middle insulation layer, an inner protective layer. The outside reflective layer may include Mylar® polyester film or aluminized polyester film or similar material, and the emissivity of outer layer may be less than 0.40 (0.05-0.40 is a preferred range), or in any range provided herein. The first middle insulation layer may include nylon or polyester Rip Stop material similar to 70D Rip Stop Nylon. The second middle insulation layer may include a ⅛-⅜″ thick open cell insulation foam which provides buoyancy and additional drop/shock protection for the device. The inside protective layer may include a micro-fleece type material (lining) which protects the touch screen on the device and prevents scratches.

A second four-layer embodiment provides an outer protective double layer which includes a layer of printed Rip Stop Nylon or similar material and a highly reflective “continuous” metalized Mylar® polyester film, or aluminized polyester film laminated to a Rip Stop Nylon or similar material. Further, in embodiments, the surface of the outer reflective layer has a reflectivity in the range of between 80% and 100%, with a preferred range between 90% and 100%. Further, this embodiment includes a middle insulation/air space layer and an inner protective layer. The middle insulation layer may include ⅛-⅜″ thick open cell insulation foam which provides buoyancy and additional drop/shock protection for the device. The inside protective layer may include a micro-fleece type material (lining) which protects the touch screen on the device and prevents scratches.

A third four-layer embodiment provides an outer reflective layer, a first middle insulation layer, a second middle insulation layer, an inner protective layer. The outside reflective layer may include Mylar® polyester film, such as a highly-reflective “continuous” metalized Mylar® polyester film, or aluminized polyester film laminated to a Rip Stop Nylon or similar material, and the emissivity of outer layer may be less than 0.40 (0.05-0.40 is a preferred range), or in any range provided herein. Further, in embodiments, the outer metalized surface of the outer reflective layer has a reflectivity in the range of between 80% and 100%, with a preferred range between 90% and 100%. The first middle insulation layer may include nylon or polyester Rip Stop material similar to 70D Rip Stop Nylon. The second middle insulation layer may include a ⅛-⅜″ thick insulation foam (which can be either open cell or closed cell) which provides buoyancy and additional drop/shock protection for the device. The inside protective layer may include a micro-fleece type material (lining) which protects the touch screen on the device and prevents scratches.

In aspects, an additional layer may be included between the third and fourth layer, between an innermost layer and another layer, or between any layer, wherein the additional layer may comprise a phase change material (PCM), aerogel (e.g., a synthetic porous ultralight material derived from a gel, in which the liquid component for the gel has been replaced with a gas without significant collapse of the gel structure, resulting in a solid with low density and low thermal conductivity), or similar low conductivity material as would be understood by one of skill in the art.

According to embodiments, a closure can be provided to close the protective sleeve, which closure may be a plastic spring strip closure or other closure system such as a hook and loop closure or similar type of closure. However, according to embodiments, the closure may be configured so that it does not seal the sleeve and thus allows thermal energy to dissipate through. Further, any embodiment may include a woven tag which provides a user ID on the tag.

Turning now to the figures, FIG. 1A shows an embodiment of a protective sleeve 101 during use. At the top of the protective sleeve 101 is a reinforced closure 105 for closing the sleeve over a cell phone during use. Also shown are one or more internal seams 115 which can be used to bind together the various layers of the protective sleeve. The internal seams may be provided at the bottom and sides of the protective sleeve to join the various layers together, while leaving an opening at the top of the protective sleeve where the reinforced closure is provided. At the bottom left is a woven tag 195 for indicating branding or personal identification indicia, however, such a tag can be placed anywhere on the protective sleeve. Further visible is a window 120 and a cover 122 connected to the sleeve 101. FIG. 1B schematically shows that the structure 100A of the various layers of a 4-layer embodiment may be generally implemented as an outer reflective layer 125, a first middle layer below the outer reflective layer which is a durability layer 130, a second middle layer below the first middle layer which is an insulation layer 135, and an inner layer below the insulation layer which is a protective layer 140. It should be pointed out that the inner layer may or may not be an antimicrobial layer. FIG. 1C shows that this structure 100B of the 4-layer embodiment may be specifically implemented as an outer Mylar® layer 155, a first middle layer which is Rip Stop Nylon 160, a second middle layer which is open cell foam 165, and an inner or interior layer which is by way of example only, one of a micro fleece, polyester, fabric, or textile liner 170.
